There are many possible failure modes, and each exercises a different aspect of resilience. Another problem is that a design control, intended to mitigate a failure mode, may not work as intended.

Site performance is potentially the most important metric. The better the performance, the better chance that users stay on a page, read content, make purchases, or just about whatever they need to do. With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. Lighthouse.

And asserted conditions only evaluated if they’re enabled, so any side effects won’t happen when they’re not enabled; they might sometimes perform local side effects, such as to do logging or allocate memory, but the program should never rely on them happening or not happening. Assertions are only about finding bugs, not doing program work.

In some cases, if only a very few, these assets continue to be used because they still work very well, were thoughtfully designed, and have been well cared for over the years. A basic premise is that there are alternatives to traditional "lift and shift" strategies by retiring legacy assets in a piecemeal fashion.
